She demanded the federal government to file an immediate appeal to the Supreme Court of Canada.

"This ruling is bad for working families," Notley said. "And it's bad for the security of our country, the economic security of our country. Albertans are angry. I'm angry."

In addition, Notley said that she's pulling Alberta out of the national climate plan "until the federal government gets its act together".

Alberta's withdrawal from the national climate plan will occur when the federal carbon tax reaches $40 per tonne.

Notley also called on the federal government to immediately recall Parliament to fix the National Energy Board process.

The Federal Court of Appeal found that the NEB decision failed to take into account the potential impact of the pipeline on endangered southern resident orcas. If the project is completed, it's expected to lead to a seven-fold increase in oil tanker traffic in the waters off Vancouver and in the Strait of Georgia.

Notley also urged the federal government to "improve consultation and accommodation to Indigenous people".

The court ruling determined that Ottawa did not engage in meaningful consultation with several First Nations on the pipeline project in accordance with its legal requirements.

"That part of it, in my view, is capable of being fixed," Notley said. "It's a delay, but not a fatal delay."

She claimed that if these steps were taken, construction on the project could resume by early next year.

The court decision came on the same day that Kinder Morgan shareholders were scheduled to vote on the sale of the company's Canadian assets to the feds for $4.5 billion. As part of the deal, Ottawa is on the hook for spending another $9.3-billion to triple shipments of diluted bitumen through the system from Alberta to Burnaby.

Notley claimed that under current circumstances, Alberta oil can only reach tidewater through the United States. And she insisted that as a result, Albertans are not getting a fair market price for their resource.

"When Alberta's economy is held hostage, Canada's economy is not working," she said.

Premier John Horgan, on the other hand, tweeted that British Columbians have been saying that the Trans Mountain Expansion Project would "create serious risks" to the coast.

"Today, the Federal Court of Appeal has validated those concerns," Horgan said.

Squamish Nation councillor Khelislem pointed out on CBC News that it was the current federal cabinet under Justin Trudeau, and not the Harper government, that approved the project.

"I've said today and I'll continue to say that Trudeau needs to stop picking fights with Indigenous people. And today's an example of that," Khelsilem told CBC. "We don't want to be in court fighting the federal government. But they're choosing to do that."

Vancouver mayoral candidate Ian Campbell—who's on leave from his position on the Squamish Nation council—tweeted a video of a speech that he gave about the need for leaders committing to "100 percent renewable energy".
